More children have been killed in Gaza than all conflicts combined from the previous 4 years. That's not even touching all of the Palestinians that Israel has murdered prior to Oct 7th.
I don't know why you think that. I have a feeling that you live far from war.
For what it's worth, quite a few children that I know or whose parents I know were murdered on October 7. Two of them were babies, burned alive, one of those babies was an infant. And a child in my daughter's class was murdered, along with both his sisters (and both parents, too). Shall I go on?
